HI !
Human Digestive System :-
The nutrition of human beings [ or man] takes place through human digestive system.The human digestive system consists of the alimentary canal and its associated glands.The various organs of the human digestive system are : Mouth , oesophagus , stomach , small intestine , large intestine .The glands associated with the human digestive system are : salivary glands, liver and pancreas.
=========================================
Process :-
The mouth cavity [ buccal cavity ] contains teeth , tongue and salivary glands.The teeth cuts the food into small pieces , chew and grind it .The salivary glands in our mouth produce saliva , which makes the food soft , so that it can be swallowed easily.Human saliva contains an enzyme called salivary amylase , that digests the starch present in the food into sugar.
The partially digested food in the mouth is swallowed by the tongue and goes down the food pope called oesophagus. The oesophagus carries food to the stomach.
The peristaltic [ contraction and expansion ] movement of food pipe allows the food to pass into the stomach.
The stomach is a J shaped organ.The stomach contains glands , which produce gastric juices,This gastric juice contains Hydrochloric acid, pepsin[enzyme] and mucus.
HCl makes the medium acidic , for the pepsin enzyme to act on the food and break down protein present in the food.HCl also kills microbes that my enter along with the food.Mucus protects the inner lining of stomach from the action of HCl.
From the stomach the partially digested food enters small intestine . Small intestine is the place where complete digestion of food takes place.
The small intestine receives secretions from two glands: liver and pancreas
Liver secretes bile juice, stored in gall bladder.Bile is alkaline in nature , and contains bile salts which helps to emulsify or break the fats present in the food.Bile juice makes the acidic food alkaline so that the pancreatic enzymes can act on it , and also the bile salts breaks the large globules of fat into small globules .
Pancreas secretes pancreatic juice , which contains enzymes like trypsin [ protein digestion] , lipase [ fat digestion ] and pancreatic amylase [breaks down starch]
The walls of small intestine secretes intestinal juice.This juice contains enzymes which complete the digestion of complex carbohydrates into glucose, proteins into amino acids, and fats into fatty acids and glycerol.
The inner surface of small intestine contains small finger like projections called villi , which increases surface area for absorption , and is richly supplied with blood vessels.

In the digestive system, all the organs are involved that do the job of chewing, swallowing, digesting and absorbing food besides extracting unprotected food. It consists of various body parts, including various digestive organs.
Come know your digestive system:
Esophagus
The esophagus is about 25 cm (10 in) long and a narrow muscular tube that is approximately 2 cm wide, which starts with the pharynx behind the mouth, passes through the thoracic diaphragm from the thoracic end and ends by moving the heart in the abdomen.
The wall of the esophagus is made up of two layers of thin muscles.
On the top of the esophagus there is a line of tissues called epiglottis which closes up during swallowing, so the food can not enter the trachea.
The chewing food is pushed through the esophagus to the abdomen through the peristalsis of these muscles.
It takes only seven seconds for the esophagus to pass through food and during this time the digestive tract does not occur.
Stomach
Between the stomach, esophagus and diarrodynas, under the diaphragm, the scalp of part of the spleen and partly the liver is the sore part of the nutrition tube.
Most of it (approximately 5/6) is located on the left side of the body's middle line and the rest is on the right side.
Next to it is the left section of the liver and the front ventral wall.
The abdominal aorta, pancreas, spleen or spleen, the left renal and adrenal gland are stable behind it.
Above it is the left cell of the diaphragm, esophagus and liver.
The lower intestine has the transverse collar and there is a small intestine.
On the left side there is the diaphragm and the spleen and the right side of the liver and diorodynas.
It is made up of fundas or upper part of the body, part of a function or middle part, and gastro-output or pylorous or remote small area. It releases gastro-juice, which is mixed with food and is suitable for further digestion through the intestines. Chaim creates a semi-aromatic substance.
Small intestine
It is smaller in the intravenous than the large intestine.
It extends from the gastrointestinal tract to the end of the ileum or ileum, on the elliosical valve, the 5 to 7 meter long tube open in the large intestine is.
It is longer in men than in men and due to the decrease in tone, it is longer in the dead body than living body.
It usually lives in the middle of the large intestine in the lower middle part of the abdomen.
It has the following three parts:
1. Concentration or Duodenum
This is the first part of the small intestine that spreads from the Pyelorus to Jejunam.
It is about 25 cm (10 in.) Long by coming in the horse's cord (the letter c in English), which is surrounded by the pancreas or the top of the pancreas.
A bilateral hole on the distance of about 10 cm from the pylorus, the opening of the waiter and the normal biliary duct in the ambulance of the waiter comes both.
It is surrounded by muscular muscles.
2. Manthan or Jejunum
This small upper part of the episode should have an upper 2/5, and about 2.5 meters (8 feet) tall.
Its upper end is dyedinum connected.
3. Experiment or Ileum
This lower part of the small intestine, from the junction of the lower extremity or part of the egg or sacum which is about 3.5 meters long and ends on the ioliosical valve, which controls the flow of food in the large intestine with ileium, Prevents back from coming to the ileium.
There is no clear boundary between jejunum and ileums. The geese and ileum part of the small intestine are hanging from the abdominal wall by a folded fold of the peritoneum or a folded fold of the paritonium, called a mengentry.
4 Large intestine or colon
It is a distant part of the intestine that extends from its confluence to the anus with approximately 5 ft tall and small intestine, and is formed from conjunctiva, colon, rectum and rectal tube.
The entire large intestine is also called macro-colon.
The macro-division is divided into three parts - ascending, transverse and descending part.
